But it's Hulk Hogan and there's no argument. When I hear "wrestlemania" I think of Hogan's moments as they seep into the mind.
As stated

The main event of the first Mania.
The biggest match of all time with Andre the Giant at Mania 3.
A top 10 top 5 biggest mania match of all time with a superstar that has surpassed him mainstream wise.
Mega Powers Collide
The Ultimate Challenge
Basically being the MAIN attraction or ONE OF the main attractions at 10 mania in terms of the marketing and outcome of the event.
Real American vs the "traitor" in Sgt Slaughter in a highly controversial angle.

That impact just can't be matched, not even by Taker, HBK's greatness performance wise, Austin vs The Rock, Cena, etc.
